This work is concerned with the design design full functional nodes and to evaluate an application in wireless sensor network. The resulting designed product could form a reliable support for transferring data between nodes and a computer. MaxStream XBee ZNet 2.5 modules are chosen as the radio platform and LabVIEW as the virtual instrument for user interface.

The target of this work is to modernize air-conditioning control of the unit Thermal Chamber. The old air-conditioning unit will be renewed by replacing old one by new one, microcontroller-driven control unit, trough which it will be possible to show the current and desired temperature LCD. Theoretically description of the components and methods of measuring the temperature and environment for the creation of the microcontroller is shown before construction.

We need to employ modern-day technologies in our daily lives to make our life easier. In this thesis, we analyze the user’s oral hygiene habits and core body temperature to help people to track the state of their health. We designed a system in which the data are directly extracted from the mouth, then stored and presented in the application. By means of the system, the people can keep track oftheir core temperature without any extra function apart from their daily chores.The system can also help to keep track of the health of people with symptoms ofdementia and Alzheimer. We used an LM35 temperature sensor to measure temperature. The sensor is mounted on a powered toothbrush head. When the user starts to brush, the sensor records the temperature data for seven times in two minutes of an average brush time and sends it to the mobile application using WiFi. We used a NodeMCUboard, ThingSpeak server and MIT inventor app to transfer the data and designthe mobile application.
